⚙➡🍄 In this video I will teach you how to build a air ventilation system for your martha that is water proof. This is needed, because you will have a high humidity content and you also will have lots of spores in your tent. That is why it will also create an under pressure. In that way no spores will be released into your home!

Printed on an Ender 5 Pro with direct extrusion and a 0.6 mm nozzle. White PLA.
